Sam Gyimah: My hon. Friend is absolutely right. Were the UK not to continue to participate in the Galileo programme, not only would the programme be delayed but it would cost EU member states a lot more. Surrey Satellite Technology has been responsible for the cryptography and encryption of the Galileo system, and CGI UK, which has a presence in Surrey, has been responsible for building a number of the satellites. So the expertise and skills necessary to deliver the Galileo system reside in the UK, and were the EU to adopt what I consider to be an irrational position and not allow the UK to fully participate, we would not only take the action we need to take to protect critical national infrastructure, but we would also be at liberty to partner with other countries around the world, not only to develop our own global navigation and satellite system but to develop our space sector.
